On my machines, catwalk is not able to manage joins. Clicking the "save" button didn't appear to have any effect.
After some digging, I found that applying the patch[1] linked at the bottom of this message fixed the problem. My question to the list is two-fold: 1) Am I the only one seeing this problem? 2) Would this be the correct python idiom for solving this?
